ABSTRACT:
A portable evaporative cooler is constructed from a housing having at least one opening fitted with an evaporative medium pad, and an exhaust vent. This cooler includes a pump for dispersing water over the evaporative medium pad, and a bottom pan for receiving the water, the pump cooperating with the bottom pan to permit water to recirculate. A fitting on the housing permits the cooler to be connected to a water source, the fitting including a valve (such as a float valve) for automatically filling the cooler when the water level in the bottom pan is below a predetermined level. An exhaust fan draws air into the housing through the evaporative medium pad and out the exhaust vent. Finally, the housing is fitted with a convenience device (such as a beverage server or tool tray).
